I am trying to diagnose a nagging bog while accelerating from, say, 40 MPH and stabbing the gas to accelerate.
I removed my Motorcraft 2100, and while keeping it upright, I removed the power valve cover from the bottom of the body. There was a small amount of gasoline in the power valve cover and the power valve itself was wet with fuel but not leaking any out. Is this normal or does this mean I should replace the power valve?
I would think it's normal to have a bit of fuel sitting in the power valve cover since I ran the engine only a few weeks ago but I wanted to check with the board, here. I replaced the power valve about 8 or 9 years ago when I rebuilt the 2100 but I don't remember if there was gas in the power valve cover when I removed it at that time.
I mainly suspect the accelerator pump diaphragm as one of the causes of the bog. When I checked that, the rubber diaphragm seemed to be kind of flimsy and not so firm like a new rubber one would be. I replaced it.
